It's no secret that investing magnate Ray Dalio is a big proponent of meditation — after all, he once said it made him feel like a "ninja in a fight."

But you've probably never seen him chatting about it with critically acclaimed film director Martin Scorsese, who has been practicing transcendental meditation since 2008.

The two legends spoke with the executive director of the David Lynch Foundation, Bob Roth, during a private fundraising event in January, about how transcendental meditation keeps them grounded in their fast-paced industries.

"I started in 1968 or '69 and it changed my life. I was a very ordinary — sub-ordinary student," Dalio said. At the time, he was studying at Long Island University. "It brought me a clarity, it made me independent, it made me free-flowing, it just gave me lots of gifts."

Dalio, worth about $15 billion, now runs the world's largest hedge fund.

Scorsese, known for many films including the 2013 dark comedy "The Wolf of Wall Street," said he practiced transcendental meditation daily — twice a day if possible.

It helped him through the harrowing production of his first 3-D picture, the 2011 children's film, "Hugo."

"In the morning I would get up 45 minutes earlier to do meditation before I was able to face that set, with children actors that can only work for like for a minute, a dog that wasn't listening, and Sacha Baron Cohen was improvising everything, and everything in 3D — and over schedule and over budget!" Scorsese said.

"So, God, there's only one thing you can do, is calm it down. Get into it, and deal with the realities."

When he had an unsolvable problem, Scorsese would sit down and meditate.
